However, to discover potential target cells for handovers there are three possibilities for the UE 15 as in FIG. 1. For example there is:
  • An Event A3 is defined as the scenario where “Neighbor Cell has become better than serving cell plus a given threshold”, which means there is a neighbor cell that potentially offers better connectivity for a given UE. In pure formulation it can be written as:
